Answer:
The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
Explanation:
The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.
It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.
Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.
The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.
Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
- <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
- <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
- <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>
Answer:
The temperature and rainfall change at different times of the year.
Explanation:
A temperate climate region is a territory in which the climate cannot be classified as completely hot or cold, nor rainy or dry, but these characteristics are variable according to the season of the year in which it is found. Thus, these climates do not have extreme heat or cold temperatures, but rather moderate climatic conditions. An example of a region with a temperate climate is the Mediterranean region, the State of Georgia in the USA or Uruguay.
Non-fluorescent calcein AM is hydrolyzed by intracellular esterases into the green fluorescent dye calcein, which can be used to quantify the number of viable cells.
